40 percent of 25 students is 10.
It is 2.22... (recurring) percent.

Hello
It is a good idea to always review a test or quiz before it is turned in. This might help the student find incorrect answers, and correct them.
The student most likely mistakenly swapped the percentages of NaCl and SiO2 in her calculations. She likely misinterpreted the data or made an error in transposing the numbers during the calculations.
Without seeing the drawing, it is difficult to pinpoint the exact issue. However, potential problems could include incorrect placement of reactants and products, missing or extra elements, incorrect chemical structures, or incorrect stoichiometry. The student should review the reaction equation and ensure that the drawing accurately represents the chemical reaction.
To calculate the percentage, divide the number of correct answers by the total number of questions and then multiply by 100. In this case, the calculation would be (71 correct answers / 85 total questions) × 100, which equals approximately 83.53%. Therefore, the student would receive a score of about 83.5%.
3/40 = 0,075 0,075 x 100 = 7,5 % 100% - 7,5 % = 92,5 % correct
The probability of getting at least 1 correct answer is equal to one minus theprobability of answering all incorrect, this would be;P(atleast 1 correct) =1 - P(allincorrect) =1 - (1/2)8 =1 - 0.00390625 ~~ 0.9961 ~ 99.61%
Neither is correct. You would say "There are no students" or "There is not one student" or "There are not any students."
The correct terminology between an honor student or a honor student depends on how it is being used. The most common way it is used would be an honor student.
